HOSE-FCOUPLITNG.

SPECIFICATION forming part of Letters Patent No. 734,377, dated July 21,1903.

Application filed March 3, 1903. Serial No. 145,886. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK Tonnes, a citizen of the United States ofAmerica, residing at Vilkinsburg, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements inHose-Couplings, of which the following is a specification, referencebeing bad therein to the accompanying drawings.

This invention relates to certain new and useful improvements inhose-couplings; and the invention has for one of its main objects toprovide novel and effective means for joining the two sections ormembers of the coupling together without the use of the ordinarythreads.

A further object of the invention is to construct a coupling of thistype wherein a perfectly smooth bore of equal diameter throughout thelength of the coupling is provided, thus affording no impediment to thewater in its passage from one section of the hose through the couplingto the other'section of the hose.

Other objects of the invention reside in the novel construction offastening means for securing the two sections or members of the couplingtogether, the form of joint between the two sections or members, and inother features of construction, as will be hereinafter more specificallydescribed, and then particularly pointed out in the accompanying claim.

In describing the invention in detail reference will be had to theaccompanying draw.- ings, forming a part of this application, andwherein like numerals of reference will be employed to designate likeparts throughout the different views of the drawings, in which Figure 1is a top plan View of my improved hose-coupling, showing the members orsections in the coupled position. Fig. 2 is a central longitudinalsectional view of the same. Fig. 3 is a detail perspective viewof a partof the fastening yoke or device, showing a part of one of the sideplates engaged by said yoke. Fig. 4. is a detail side elevation in thecoupled position of a modified form of construction. Fig. 5 is a topplan view thereof, partly broken away, showing the yoke in section.

To put my invention into practice, I provide a male member 1 and afemale member 2. The male member 1 is constructed near its engaging endwith an annular integral collar 3 to form a seat for the engaging end ofthe female section or member, and at its engaging end the male sectionis beveled or inclined, as shown at 4, and this inclined or beveledsurface seats against a flexible gasket 5, that is placed within thechamferedout receiving end of the female section or member, the gasketseating against an annular inclined or beveled seat 6, havingsubstantially the same bevel or incline as the beveled surface 1. Thefemale section or member being chamfered or recessed at its receivingend to receive the male section or member, the bore is consequently ofthe same diameter at the joint as throughout the remainder of thesections or members, and no impediment is offered to the free passagethrough the coupling of the water. Affixed to opposite side faces of thefemale member are plates7, to which are pivotally'secured at 8 the sidestraps or arms of the securing-yoke, embodying in its construction thepair of side straps or arms 8 and the connecting strap or band 9, curvedto pass over the coupling and when closed to lie in engagement with themale section, as seen in Fig. 2, the same being notched or turned up atone edge, as seen at 10, in order to permit the catching of the same forlifting to uncouple the members or sections. The side straps or arms areextended some little distance beyond their pivotal point and curvedupwardly slightly, and pivotally attached to these extending ends 11, asat 12, are forwardly-extendin g arms 14, provided at their outer endswith upwardly-extending lugs 15, which engage the inner face of the sidestraps or arms 8 at the ends of thestrap or band 9 when the latter is inthe closed position. These arms are held by reason of the shoulders 16thereof en gaging with the annular collar 3 of the male-section ormember. As the strap or band 9 is raised and thrown back upon the femalemember the lugs 16 will be forced forwardly away .from'the collar orflange 3, and as the strap or band is forced down on the male sectionafter the sections have been joined together the lugs 16 of the flangeor collar. When these arms are forced outwardly at their forward ends,these forward ends of the arms will drop by rea son of their support atthis forward end having been removed; but when the lugs are drawn intoengagement with the collar or flange 3 the arms will be held at theirfree or outer ends, as well as at the rear or pivoted ends thereof,since the arms cannot fall or swing downward at their outer ends so longas the lugs 16 are in engagement with the collar or flange 3.

In Figs. 4 and 5 I also attach the side arms or straps 8 to plates 7,attached to the opposite sides of the female section, the plates 7carrying journal-pins 17, extending beyond the outer face of the sidestraps or arms, and having seats in their outer ends to receive the pinscarried by the arms 14. The forward ends 19 of these arms 14' are bentinwardly to engage with the collaror flange, and in order to spread thearms to permit the engagement and disengagement of the sections Iprovide a boss 20 on the inner face of the arms 14!, near the upper edgethereof, and on the outer face of the female section provide bosses 22.As the band or strap 9 is opened and moved back onto the female sectionthe arms 14 are moved forwardly, and the boss or cam 20, engaging withthe boss or cam 22, spreads the arms, so as to move the forward endsthereof outwardly, in order to permit the engagement and disengagementof the sections. This spreading or outward movement of the forward endsof the arms is possible by reason of the pivotal joint of balland-socketform at the rear or pivoted ends of the arms, this joint permitting therear ends of the arms moving inward as the forward ends thereof spread.The shoulder on the cam 22 holds up the arms by reason of the cam 20resting thereon, thus preventing the arms from dropping when the .yokeis operated.

While I have herein shown and described the invention in detail in twoof its forms as it has been practiced by me, yet it is evident thatvarious changes may be made in the details of construction withoutdeparting from the general spirit of the invention.

Having fully described my invention, what Iclaim as new, and desire tosecure by Letters Patent, is-

The combination of the pipe-sections one of which is formed with acollar, of a yoke having its free ends pivoted to the opposite section,and a pair of arms pivoted to the rear portions of the said yoke, andprovided at their free ends with inwardly-projecting lugs engaging saidcollar, said yoke being adapted when in a closed position to engage theinwardly-projecting lugs of the pivoted arms, substantially asdescribed.

In testimony whereof I affix my signature in the presence of twowitnesses.

FREDERICK TOERGE.
